A process and apparatus are disclosed contacting hydrocarbon feed with catalyst in a reactor vessel under conditions more vigorous than bubbling bed conditions and preferably fast fluidized flow conditions. The vigorous conditions assure thorough mixing of catalyst and feed to suppress formation of dry gas and the promotion of hydrogen transfer reactions.
